Safe grating, as an important industrial safety protection device, is widely used in modern industrial automation production lines and robotics workstations. Its core function is to monitor the working area in real time to prevent personnel from accidentally entering the dangerous area to effectively ensure the personal safety of operators.Avoid injury accidents caused by improper human -machine interaction.The following will be introduced in detail from the working principles, classification, application areas, and selection and installation precautions of the safe grating.
working principle
Safe grating is usually composed of two parts: transmitter and receiver.The transmitter emits a series of parallel infrared beams, and the receiver is responsible for receiving these beams.When the beam is not blocked,ADG412BRZThe receiver will continue to receive the signal and keep the machine running normally. Once an object enters the beam range, the beam is blocked, and the receiver will not be able to receive the corresponding signal, thereby triggering the security mechanism and stopping the machine to stop operation.
International security standard
(1)、ISO 13849-1: This is a standard for assessment principles related to the safety control system of mechanical security control systems.It provides a framework for assessing the safety control system, including the safe grating, to ensure that it reaches the predetermined safety performance level (PL,Performance Level)。
(2)、IEC 61508: This is a common functional security standard, which is suitable for the safety life cycle management of all types of electrical, electronics, and programmable electronic security -related systems.The design and manufacturing of the safety grating must meet this standard to prove that they can reliably execute the security function in the expected application environment.
(3)、IEC 61496: This is a safety standard specifically for photoelectric protection equipment (such as safe grating), divided into two parts:IEC 61496-1 For the safety equipment for fixed installation, and IEC 61496-2 For mobile devices.These two parts specify the performance requirements, test methods and installation guidelines of the safety grating.
Classification
According to different use needs and scenes, the safety grating can be divided into multiple types:
1Fixed safety grating: suitable for fixed operating areas, the number of beams and layouts are fixed. Once the installation is completed, the protection area is determined.
2The adjustable safety grating: The beam spacing can be adjusted according to actual needs, and the flexibility is high, suitable for different sizes of protection areas.
3, Control the safety grid with both hands: require operators to use at the same timeTwo hands start the device to ensure that the body is far away from the dangerous areas, and it is suitable for a high -risk operating environment.
4Laser scanner: scan the entire area by rotating laser heads, suitable for safety protection in complex shapes or irregular areas.
5Light curtain: forming a continuous light wall with large coverage area, suitable for personnel entering and exit in open areas such as doors and channels.
Application field
Safe grating is widely used in various industrial fields, including but not limited to:
● Automobile manufacturing: In the links of stamping, welding, assembly, etc., the operator is protected from the damage of the robotic arm or mobile components.
● Electronic manufacturing:SMTProduction lines, automated assembly cables, etc. to ensure the safety of people around the automated equipment that operates at high speed.
● Logistics warehousing: In the automatic warehouse and sorting system, prevent personnel from entering the path of automated transportation vehicles or stackers.
● Food processing: Provide safety protection on the production line that needs to be hygienic and frequent contact with personnel.
● Packaging printing: High -speed packaging lines, printing machines, etc., to prevent operators from approaching the mechanical part of fast operation.
Select and install precautions
1Risk assessment: Before selecting a safe grating, detailed risk assessment should be performed to determine the required safety level and protection area.
2Response time: Select the corresponding response safety grating according to the specific requirements of the application to ensure that the hazardous actions can be stopped in the shortest time.
3Installation location: The grating should be installed at the entrance of the dangerous area to ensure that there is no blind area and avoid external light interference.
4, Maintenance and Check: Regularly enter the safe grating inClean and functional inspections to ensure that it is always in a good working state.
5, Compliance: choose to meet international security standards (such asISO 13849、IEC 61508Wait for products to ensure legal compliance.
As an important part of modern industrial safety production safety, safety grating provides operators with a solid security barrier through its high sensitivity and reliability. It is the key to realize the harmonious coexistence of man -machine, improve production efficiency, and ensure sustainable development of enterprises.One of the equipment.
